MEMMOVE(3)              Linux Programmer's Manual             MEMMOVE(3)

NAME         top

       memmove - copy memory area

SYNOPSIS         top

       #include <string.h>

       void *memmove(void *dest, const void *src, size_t n);

DESCRIPTION         top

       The memmove() function copies n bytes from memory area src to
       memory area dest.  The memory areas may overlap: copying takes
       place as though the bytes in src are first copied into a
       temporary array that does not overlap src or dest, and the bytes
       are then copied from the temporary array to dest.

RETURN VALUE         top

       The memmove() function returns a pointer to dest.
